Application March 21,

Claims.

This invention relates to a safety catch for pin stems and the like andhas for one 01' its objects the provision of a complete catch and inaddition a locking gate therefor which will be securely held across theentering opening for the pin stem to prevent accidental detachment ofthe pin stem from the catch.

Another object of the invention is the provision of a safety catch whichmay be made inexpensively and of a minimum number of parts and cut outin multiple and assembled by machine tool operation thus reducingexpense of construction.

Another object of the invention is the provision of a construction inwhich the pin stem will assist in maintaining the gate in closedposition.

Another object of the invention is the location of the gates that thebase may be engaged to drive the points thereof into the ornament.

Another object of the invention is the provision of a construction inwhich the pivot point about which the gate will rock may be formedintegral with one of the ears and positioned in an opening in the gateby a folding operation.

A further object of the invention is the provision of a finger piecewhich, in addition to its function of serving to manipulate theswingable gate, also serves as a stop to limit the opening movement ofthe gate that it may always be in a position for convenient operation bythe user.

With these and other objects in view, the invention consists of certainnovel features of construction, as will be more fully described, andparticularly pointed out in the appended claims.

In the accompanying drawing:

Fig. 1 is a perspective view of the back of an ornament showing a pinstem and safety catch as provided thereon.

Fig. 2 is a perspective view of the safety catch as cut out from sheetstock.

Fig. 3 illustrates the safety folded into finished position.

Fig. 6 is a central sectional view showing the gate in open position.

Fig. 7 is a sectional view on line 7-7 of Fig. 5.

Fig. 8 is a view similar to Fig. 5 showing a modified form of gate.

In the use of safety catches on bar pins, ornaments, badges and thelike, it is necessary to provide a catch which will secure the pin stemin position and in addition to such a catch it is desirable to provide alocking device which catch as partially 1933, Serial No. 661,866

will prevent the pin stem from being accidentally removed from thecatch, and in order that this may be obtained in a simple, efficientmanner and one which may easily I have cut out and provided the same sooperate conveniently and a catch from sheet stock that it will functionregardless of a gate or locking device, and then have additionally viceto cooperate cidental disengagement the arranged by integral pivot thatthe parts may be ing the catch into its provided a gate or lookingdewith the catch and prevent acrefrom, and K have so and recess openingsassembled by merely foldfinished position with the gate so located thatthe catch may be driven into an ornament if desired, and

is a detailed description of ment of this invention illustrating thepresent embodithe preferred means by which these advantageous resultsmay be accomplished.

With reference to the drawing, is designates a bar pin or ornament whichis provided with a hinge joint 11 pivotally mounting a pin stem 12 whichswings about the pivot 13 and engages the stop is that tension may beapplied on the pin stem engaging with the shown blanked out in F'g.

catch. The catch is 2 which consists of a flat piece of stock 15 cut outin the shape there shown with an integral portion 16 forming a pivot pinraised from the stock thereof.

This blanked out form is folded as at 17 and 18 providing a base 19 withcars 20 extending upwardly from either side of this base and attachingprongs so folded downwardly from the ends of the base.

These ears are each hook shaped providing a shank portion 21 and anopening 22 into which the pin stem 12 may be positioned and by reason ofits resiliency will move to engage upper portion 23 of the arc of thehook to retain which is a shape the same are on substantially ally ofthis shape for will more fully hereand 21 I have mountshown in Fig. 4begenerally conforming This gate is provided with an ear 26 having apierced opening 2? which receives the integral pin 1 this gate betweenthe ears 2 6 to pivotally mount 0. Pivot 16 is located along the shankportion 21 of the hook so that the gate when moved to closed positionsubstantially conforms to the shape of the hook and extends across theopening the exit of the pin stem 12 the catch.

22 thereto to prevent for detachment from the following In order thatthis gate may be easily manipulated I have provided a finger piece 28which is 50 located that it will engage the base 19 as will be apparentfrom Fig. 6 to limit the opening of the gate from its locking position.This limiting will be in such a position that the gate 25 may be readilyengaged for closing the gate or moving it to the position such as shownin Fig. 5 with its end portion 29 across the opening 22.

In order to better retain the gate in position there may be provided, asin the modified showing in Fig. 8, a projection 31 which will be forcedpast the resilient pin stem and with which the pin stem engages shouldthe gate tend to accidently open, there being required considerablepressure to open the gate by reason of this locking projection. Thus anadditional safety feature in the catch is provided which is desirable toprevent loss of a bar pin ornament or the like in connection with whichthe same is used.

The prongs 30 of the base which I have provided affording convenientattachment to a celluloid object into which they may be driven, or aflat base without these prongs may be used, by soldering some otherattachment to a metal base. It is, however, a feature of thisconstruction that the gate swings out from across the base so that thebase may be engaged by a tool to drive the prongs into a celluloid orlike mounting for the catch.

The foregoing description is directed solely towards the constructionillustrated, but I desire it to be understood that I reserve theprivilege of resorting to all the mechanical changes to which the deviceis susceptible, the invention being defined and limited only by theterms of the appended claims.
